Question

if the water level at the lake continued to change at the same rate for 3 months in a row, explain how you could estimate the total change in the water level at the end 3 month period

Answer 1

Water level at end of the 3 months = 3* -1 = -3 feet.

Explanation:

Here the water level at a lake continued to change at the same rate for 3 months in a row.

For instance, if the water level decrease, we represents it by a negative number.

If the water level increases, we represents it by a positive number.

To estimate, we try to represents the fractions in to whole number.

For instance, if the water level decreases at the rate of
`(4)/(5) \\` feet per month, which is close to 1. Since it is decreases we represents it by -1.

If the water level increases, we represent it by a positive number.

To represent the water level at end of the 3 months, we have to multiply -1 by 3.

Water level at end of the 3 months = 3* -1 = -3 feet.
